Bob, how does this really work?
I always thought the PC was just supposed to interpet signals from the ECM and replace those values with values stored in it's own map. (modem). I didn't think the PC added on top or removed from the ECMs original values. So what I'm saying is, how will the PC values/maps now be incorrect because the baseline values coming out of the ECM have changed when the PC does not add on top of those values. It just replaces them with other values.
Before you get mad, I totally respect your authori-Tie!! I'm just asking..... cause I really don't know.
V/R,
lp

THEN, you are going to have to retune your PC's as the Baseline ECM programming has been changed, and your settings are going to be off kilter for the PC to modify.....
The PC adds or deletes Percentages of Change (Fuel VE F or R), or adds or deletes ignition timing (+/- 11 degrees of curve) FROM THE BASE MAP that is installed in the ECM.....
RevXtend is a Data Copycat, that takes the settings from 5400 and copies them and allows the motor to rev higher by STOPPING the normal Tach signal, and duplicating the Fuel/Spark tables to 6000 RPM....
